What will you mostly use it for?
Across most use cases including gaming, office work, programming, modding, and content creation, the B75 Pro Max is the clear winner. Its edge comes from a much larger battery, full QMK/VIA support, a TFT screen, and a knob. The L75 only takes the lead for travel, where its ultra-slim profile and lighter weight make it a more portable companion. The L75's strength is its low-profile design, but this also limits its switch compatibility and customization depth.

Yunzii B75 Pro Max vs L75: your questions
The B75 Pro Max has significantly better battery life with an 8000mAh battery, compared to the L75's 2200mAh. The vendor states that the L75 can last up to 65 days with backlight off, but the B75 Pro Max has almost four times the capacity for longer unplugged use.
Only the B75 Pro Max supports QMK and VIA open-source firmware according to the product page. The L75 offers programmable software for Windows and Mac, but does not mention QMK or VIA compatibility.
The B75 Pro Max is the better choice for modding as it supports both 3-pin and 5-pin switches and has a standard gasket mount with multiple cushion layers. The L75 is limited to Outemu low red switches and one user review indicates even Cherry low profile switches may not fit.
Yes, the L75 is a low-profile keyboard with a height of just 24.90mm, making it much thinner than the B75 Pro Max which is 42.15mm tall. This slim design is a key differentiator for users who want a laptop-like typing angle.
Only the B75 Pro Max includes a TFT screen with a 160x96 pixel resolution. According to the vendor description, it can show battery level, date, time, operating system, GIFs, and photos, and can be customized through an online website.
Yes, both keyboards support tri-mode connectivity: wired via USB-C, 2.4GHz wireless, and Bluetooth. Each can connect to up to 5 devices, according to their respective product pages.
The B75 Pro Max is generally better for productivity due to its larger battery, programmable knob, TFT screen for status, and QMK/VIA support for creating workflow shortcuts. The L75 is more suited for desk space saving but lacks these features.
Both keyboards support Windows and Mac. The B75 Pro Max also mentions Linux and Android compatibility. The L75 explicitly mentions supporting Win/Mac dual system switching and is also compatible with Linux, Android, and iOS.
Only the B75 Pro Max includes a multi-function knob. Its default function is volume control, but it can be reprogrammed using QMK/VIA software for other commands depending on your setup.
The B75 Pro Max uses double-shot PBT Cherry profile keycaps. The L75 uses double-shot PBT low-profile keycaps, which are shallower and curved to fit fingers according to the vendor description.
